There is no Triplets.
From the recent leaks, Simo's Valkyrie "Radzgriz" is the 12th of the Valkyrie Sister. Which made the last Valkyrie we haven't seen to be the 8th Sister by default.
It was believed that this Valkyrie in the slhouette + Alvitr and Hlokk are the Triplets among the Valkyries since they looks really similar, But because this last Valkyrie is the 8th while Alvitr and Hlokk were 10th and 11th respectively, Which mean that they couldn't really be a triplets anymore.
So instead of the Triplets, It's only Alvitr and Hlokk as a Twins while this Valkyrie just simply look similar.
